Application lcd liffay 13, 1915. Serial No. 29,08.

following is-a description, reference being .had to the accompanying drawings. which `form apart of my specification.

Myinve'ntion relates Vmore especially to improvements in thehulls of boats; having for its object lthe provision of sectional steel or metallic Walls whereby a hull possessing great strength, andA yet comparatively' light in Weight,'is obtained.- A' A i Another objectof'niy invention is to provide a construction which will bel simple and easy to manufacture, economical in Another object of my invention is to provide@J a construction wherein t'he hull is foriiedjvith-double Walls spaced apart, so thattlie intervening space can be. utilized vfor the storage of fuel, ballast, and so forth;

the intervening space, by rea-son of the construction employed, being divided into Yseparate nonhcoinmunicating chambers'.

A further object of my invention is to provide a construction wherein the linll is not only provided with' a series of longitudinallydisposed chambers intermediate of the Walls, but also be provided with fluid tight transversely .arranged bulkheads, 'whereby the hull is divided into any desired number of compartments to increase the. 'safety of. myA limproved construction, thus giving. lgreater protection against the possibility' of sinking.

he advantages inherent in my improved construction Will be readily apparent vfrom the following detailed description.

Fig. 1.1 -is a fs'ide'elevation of a bull:- head as'employed in my improved constructionsshown in Figs. 6 and 7.' Fig. :12 is a cross-section' through the bulkhead taken on the line C-C of Fig. 11.

' My inve tion relates tothe hull of atboat or vessel constructed of sheet metal sections, preferably arranged-iii the manner hereinafterv -set forth; theparticular exemplification of mylinvention, as illustrated in the first 'fivefigures ofthe drawings, coinprisinga series of channel sections spaced apart so as to provide an inner and ran outer wall; the outer wall consisting 'of flanged or channeledsections 15, see Figs.=3, 4 and 5, havingtheir sides or flanged portions 1G preferably presented inwardly, as illustrated. The inner Wall is"constr ucted similarly fromrhannel-or flangedsections .17, the sides being disposed angularly, as shown at 18, similar to the sidesl 16 -Of the channels flanges of adjacent. sections so as to be ii\-"' etedv thereto by i'neaiis of tlie rivets 19V and ln constructing the vliull in the manner described. the sections 15, which constitute the outer Wall. are first properly associated and riveted to onef-side -of cach stay-slicct niuiiiber or rib 2l; tlic latter .being arranged 'lengthwise of the channelor flange sections 13. The stay-sheet inci'iibcrs .or iciiiforcii'g' 45 L member or rib. InFig. 2, I- show the ends parits 21 `are made of awidth commensurate with the space 1t is intended to provide be{ tween the inner wall and the outer wall,

and -stay-slieet members or reinforcing ribs 21 also permit the Opposite sides of the the hull of the boat, or,if desired, the ribs 21 between the respective sections, consti* tutinv the bottom portion of the hull, may

be of greater width, as clearly illustrated" in Fig. 4, than the ribs 21a arranged intermediate of the 'sections constituting the sides of the hull. By arranging the sections and reinforcing ribs in the manner just described, and as illustrated in Fig. 4, it is both sides of the boat. ,l

The ends of thefsecti'ons, constituting the' evident that the side of the hull will be provided with a ledge 22 or seat arranged along inner and outer wall/may be gi-ven any desired curvature or ghape. so as toprovide the proper bow ,-/and' stern formation, as

illustrated in Fig. 2.

The stay-sheet member or reinforcing rib, secured to the free or upper sidesof the top- -Inost flangesections, not only provides a.

suitable closure for the intervening space i -tf the top of the hull, but also provides a.

suitable finish, as can be seen Figs. 2, 3 Y .and l at 23.

The channel or flange-,sections 15 and 17 may be made of any desired length, and

' the Vends Vsecured tothe abutting ends of adjacent o`r"alinedsections in any suitable .manner, as, for' example, by having the endsV welded or bent at an .angle to the main or body-portion, namely yby flanging the ends ina manner similar to the sides of the sections. The upturned edges of thealined sections may be riveted to each other di- '.rectly or with an intermediate stay-sheet illustrated in Figs. 11- and 12, namely by employing a vseries of channel sections 24: arranged vertically, with the flanges of the intermediate sections riveted together, preferably with an intermedi-ate stay-sheet or l channel sections reinforcing member 25, as shown in'Fig. l2. As illustrated in Fig. 12, the bulkheads are preferably constructed with double one wall being composed entirely of. 24, as described, while the walls,

other wall is composed of channel sections 24: and side sections 26, in the form of Z-bars Ain cross-section; The purpose in employing sections 246 is to provide outer or f ree anges 26a .disposed in a direction opposite to that of the ang'es 24;a on the opposite Wallin order to permitthe'bulkhead to be riveted or otherwise secured into place. The free l flanges'2la and 2GA are adapted to overlap and lie lushlagainst the sections coiistituting the outer wall ef the hull, a-s more clearly shown in Fig. 2. To permit the flanges 2l and 26, ofthe transverse beams or bulkheads to be securely riveted to the sections constituting the "outer wall, the longitudinally disposed ribs, constitutingl the top rail or finishing strip 23,'are preferably cut away at two of the corners which -engage the flanges 24 and 26a, in a manner similar to the stayysheet nieinberor reinforcing rib 27, shown in' plan in Fig.

there the bulkhead construction is eniployed, it will, -of course, be understood that the walls of the bulkheads are secured to the inner surface-or side ofthe sections ,constituting the outerivall of the hull; or the bulkhead niaysiinply be secured to the secl tions constituting the inner wall of the hull and not extendthrough thelv space between the `inner and outer walls of the hull.` As illustrated in Fig. 2, the sections of the two walls are preferably so constructed and arranged as to provide aV ldngitudinal s'eain at the longitudinal center line .of the hull; and the stay-sheet member or reinforcing rib 21 is preferably made wider than the other ribs. 21, and so secured 4between the adjacent sections that it will extend soinewhat below the outer bott-om wall of the hull and thus provide akeel, as shown at, 2S infFigs. 1, 3 and' 4:.

In the .construction illustrated -in Fig. 6,

the hull is .provided with the transversely arranged stay-sheet'members or reinforcing ribs 29, which are secured between the inner and outer walls of the'hull; a portion of the double side-wall anda portion of the 'inner wall on the opposite side of the boat being shownbroken awayto the left of the gure, while a portion of outer wall of the near side of the hull is shown broken away at the right of the ligure. These ribs 29 are preferably of the same construction as rib 27, shown in Fig. 9; and are secured to the longitudinally dis osed lribs 21, as well to the flanged s ctions constituting both walls of the hull, in any suitable manner, binJ preferably "byvvelding The ribs 29 may be arranged asshown, thereby providing'a series of continuous beams throughoiit the shell or hull; or, if desired, these ribs 29 120 may be arranged in-the staggered manner illustrated in Fig-7. l ,f

The outer and inner walls of the'c'on' structions shown in Figs. 6 and 7, are coniposed of sections 15 and 17 similar in con- 125 struction to the sectionspreviously shown and described, and disposed longitudinally of the hull. The constructions shown in A Figs. 6' and- 11T -arefalso preferably provided with reinA -orcing ribs 2 1, secured `inter- 130 mediate ofi the flanges'of adjacent sections i l of both walls. a

In Figs.'6 and vided withbulkheads at 30, whichare preferably constructed as .previousl described; and more clear-ly illustrated in. igs. 11 and 12, where the bulkheads are shown composed sheet members or ribs 2 5 'with suitable airtight doors, of the compartmentsv inv thevhull, resulting' of bulkheads, may become..

filled with water, 1 to sink, as the water', by

.of sections 24 arranged to provide a double wall, spaced apart and' reinforced by stay# intermediate "sections being "omitted, or shorter sections being employed, so este provide an ,opening or doorway' 31', These openings or doorways 31 may be provided sc 'that any one from the use without causing the vessel of the .bulklieads, partment which rnay 'can be kept in the comhave become damaged;

and the cellular construction of the' hull will 5 and permit. a safe maintain the boat afloat landing. i

' The bulkheads constructed bulkheads may either be secured to the inner.

wall' in a manner as hereinbefore described, namely by riveting or otherwise securing'the flanges 245 and .26" o the bulkhead tothe sections' 17 -rconstitutingthe inner wall, or"

thebulkheads may extend through the inner i wall" and' be secured to the outer wall, as

previously-stated, in which construction the abutting sections ofthe inner wall, like -those of the outer wall, arel alsoriveted to bottom andwith` When the vesselis tobe-oi some size, .it

may be. desirable to. prq'vide thehull withl membersv extending longitudinally ofthe hull below lthe normal water-line where injury toadditioiial stiifening likely to occur.. I, therefore, illustrate the bulkhead shown in Fig. 11, provided with slots 32, 32 arranged at the sides above the a central slot 33. These slots permit the use'of inwardly extending longitudinal ribs, as shown at 34 'in Figs. 6 and 7, whereby theliull -will not'only be .greatly stiifened, but also protected against' any external obstructions encountered by the vesselgand these stieiiing ribs may be secured in place by riveting to the sectional walls, as shown, for example, at 35 in Figs. 6 and 7 or otherwise secured in place.

By constructing scribed, a very strong and yet at the saine time lightL construction is obtained, wherein the vessel is providedY witha cellular fluid- 1 tight wall, the cells or chambers being adapted for the storage of liquid fuel, lubrieating oil, fresh water, etc., while son ie of 7, I show the hulls .pro-I e 'cells on opposite closingthe doors 1' l'14A boat provided asshown. and described provide avery rigid construction adapted to resist greatiiuid pressure.
